If two materials are weldable to each other, Joseph Oat most likely has a qualified welding procedure to weld them. With our experienced team of welding engineers and welding personnel, Joseph Oat has developed a large library of welding procedures which allow Oat to weld a variety of materials, ranging from the more common Carbon and Alloy Steels and Stainless Steels, to the more difficult reactive metals including Zirconium and Titanium. A partial list of metals with which we have welding experience is shown below. Having such extensive experience in meeting ASME Section IX requirements allows us to provide equipment for most every application and end use, regardless of the corrosiveness of the service.

Joseph Oat has extensive experience in qualifying new procedures and welders for newly engineered materials. If you do not see a material listed below which you desire to use, please contact us for more information. We are certain we can accommodate your requirements.
